What do I do with the ground (GREEN) wire on the power cord, a 125V power cord?

Comment from: Ron Crawford [Member]
The green wire is not used. Follow the instructions and cut it flush as shown.

I highly recommend using a three prong extension cord and wire capping the grounds together. I know most reptile devices are two prong, however somebody not knowing could plug a three prong device in. The ground is there as a safety in case of a short, etc to lessen the risk of electrical shock. Not to mention that if a surge protector power strip was used the stray current from a power surge is sent through the ground wire.

How do i rewire it where i just can used one outlet like for instance just for a single basking light?do i use a extension cord with three outlets?

Why use the power strip and not just wire the UTH to the thermostat?
01/20/09 @ 14:46
Comment from: Ron Crawford [Member]
Dave: The power-strip gives us flexibility. We can plug multiple UTH's in the strip and piggyback off the one central probe to control heating each level in a vertical rack system.
01/20/09 @ 14:56
Comment from: Dave [Visitor]
OK, thanks.
I would assume then that for a single UTH, I could just wire up the UTH in lieu of the strip.
01/20/09 @ 15:14
Comment from: Ron Crawford [Member]
Dave: Sure but you'll place yourself into a "hard-wired" situation that's not very flexible. It's analogous to having a TV with a built in VCR unit or a phone with a built in camera. If the VCR unit breaks, you lose the ability to watch TV because you have to send the unit in for service as a whole. The same applies to a phone with a built in camera.

The better approach is to have seperate TV and VCR units that are connected via detachable cabling. If either one fails you can replace the offending unit without losing the usage of the other unit. The same applies to using a strip in our example. The power strip removes the hard-wired connection as outlined in the previous examples.

Please start a thread in the "DIY - Do it Yourself" section of our forum at http://www.RCReptiles.com/forum if you'd like to discuss this further with our members. Thanks.

Ron.
I really appreciate your time in answering these questions.

I currently use a dimmer switch and moniter the substrate temp with an infra red thermometer. I would like to set up a thermostat so I can set it and not worry about it as much.

I guess my question is: I understand the flexibilty, but isn't there only one temp probe anyways?
01/20/09 @ 16:18
Comment from: Ron Crawford [Member]
Dave: Yes, there is only one temp probe but you're not seeing the bigger picture of having a system that's flexible opposed to one that's "hard wired". If your UTH fails and you have it hard wired to the thermostat you have to dismantle everything and start over (cut wires, open thermostat, unscrew/rescrew, etc). That's not a good use of time and productivity and it introduces room for error along with safety concerns since you're dealing with electrical components. If however the UTH fails and you're using a strip type configuration all you'd have to do is replace the UTH and plug it into the strip. No dismantling required. Hopefully this clarifies the issue for you now. :-)

Thanks for your answers to my questions.
I bought and wired one up today using an extension cord with a ground wire based on Ryan's earlier comments.
The only problem I had was the gauge on the extension cord was too thick and I had to thin it out a little.
I hooked up the power strip even though I only have one tank and UTH...I may plug the CHE into it as well so it doesn't run so hot.

I am just finishing up my new tank. My BP is at the size where his 20 gal is getting a little crowded and I have been having issues wih heating and humidity because it's a glass tank. I bought a 60 gal (I know...it's a little on the large size), but I figure he will be in it for the next 20 years and I'll have lots of clutter and maybe add a third hide. This tank is also glass, but I've enclosed it with wood except for the glass front. This should take care of my heat/humidity issues...and it looks great.

I'll send some pictures when done.

Thanks again.

i can i use this ranco thermostat for on/off without relays.I want use it to control temperature in a prototype poultry incubator iam working on .I want my temperature to be between 37-38 degrees celcius.
Can i use this thermomstat without relays which are not readily available in my country?
I am wisdom ,a student from Ghana in West Africa.

Wise: Your best bet is to contact Ranco directly. I don't want to give you any information that might not be accurate so contact them directly.

I came across 3 "Double Rancos" fully assembled. I am condidering taking them apart to get 4 Singles. Any helpful feedback before I proceed?
Thanks

Comment from: Ron Crawford [Member]
Mark: I would leave them as is. They're wired in that configuration as a "back up" just in case one should fail.

Hey guys my Ranco screen and probe work fine, but my power cord does not. So I took apart my Ranco box added a new cord strip accordingly and still no power from the power strip. So once again I took it apart and this time moved the black wire from the powerstrip over one space to the farthest left opening on the black circuit box. I screwed it back up and it worked for about 12 hours and now once again my power strip does not work. PLEASE HELP

i've followed all these steps and i still had no luck the screen just stays blank. i've double and triple checked my connections and even tried with a second unit with no luck. am i idiot? i've done some wiring in the past and never had an issue before.

Perfect instructions. I, after never working with electrical wiring, have configured my Ranco. Took me 20 min. I made the change mentioned about using a grounded extension cord. Thanks!!

Thanks a ton for the guide. Just ordered 3 of these and used your guide to wire them. Saved me over $100 vs buying them pre wired!

This has been very helpful. Its always feels good to have past experiences and guidance to reply on. Very easy to wire. It took me longer to get the right small screwdriver. I did follow another posters lead and went with the three wire and joined the grounds.

Is the Ranco ETC-111000 thermostat SPDT?
Also by setting the temperature on the termostat can I control a small heater located in an other location with the 8'feet sensor? (The thermostat will be located in a different location and and the sensor will trasmit the temperature).
03/06/10 @ 09:31
Comment from: claudio [Visitor] Email
I have followed all the steps can you please answer me if I can connect on the "NC" side an other device like a refrigerator while on the "NO" side I have pluged in a small heater. Wiht both device sharing one sett point and one sensor. You see, I am curing meats in a cooler but durnig the winter months the temperature drops below the setting point therefore the heating would kick-in(operate) and viseversa if the heating goes higher then the temperature setting (although the thermostat will open) the inside of the cooler will register higher temperature than the setting point therefore the refrigerator would kick-in. Thank you.

Hi there.
I just bought this model of Ranco and I would like to install it to my cooler. I am situated in Iceland (Europe) so I will do the wiring according to a 240V. But I read somewhere that the information in the brochure to wire a 240V cord is not for users in Europe (because one end is hot and the other is neutral) ???
Have you heard of this ?
Regards
Arni

Thanks for posting in such detail. This worked great and was easier than I expected. One thing I did differently was I used only one extension cord with three inputs on the female end and cut it in half to use as both the extension cable and power strip.

Comment from: scott [Visitor]
what does UTH stand for? Also, do you have to use a power-strip, or can I just use 2 extension cords? Thanks! Cant wait to wire it tomorrow morning

sorry, just saw what UTH is...

Hi,
Those that used the 3 prong (grounded cord), how did you wire that? did you just fill the 3 slot instead of the 2 slots??

for example you connected (3 prong) ex-cord and power strip cords x 2 (slots 1 & 2) then ex-cord and 4 inch x1 (slot 3)

is this correct??


Regards
Ben,

hi will the ranco thermostat work if i wire it as it say in the manual for 240v.I have recently finished making a large homemade incubator with a capacity of 600 eggs...the only thing its missing is a thermostat..i really want to use the ranco on my incubator..would it work if i use a 220v-120v power transformer...

i was given a ranco a few years ago, its just been sitting in my closet. after doing these steps it worked perfectly! finally get to use it! thank you so much!

Great job of instructions, except:
You said to twist either wire from the extension cord to the white wire from the power strip. This could create a hazard. The ribbed side of the extension cord is connected to the larger of the two blades on its male plug. This is the neutral side and must be connected to the white wire. If it is reversed the "hot" wire from the plug would be connected to the neutral from the power strip. If a two prong device is plugged in which has a housing grounded through the neutral, this housing would now be energized and could electrocute someone.
